I have no idea how good any of the weapon types are, I just regret switching from the long haired redhead AMR sniper to the black haired glasses shotgun user because I though we would be able to keep more than one card ("currently selected characterS"). I'll just keep rolling daily till I get a 4* or get Umi again.

Or, maybe someone here knows which of the weapon types is the most useful to have starting out?

I just know this is a game I'll regret spending time on like Kanpani but what the hell.
